It is incredible what you can learn if you put your mind into it. Give yourself enough time and think about ways to learn something about the topic you would like to be an expert on, for example:

• Reading
• Take some online courses with organisations such as EdX and Coursera
• Network at events about this topic
• Find mentors

Many ambitious people pursuing a better quality of life normally beat themselves up whenever they make a mistake. They maintain this attitude with themselves and suffer under their own demands. While it ensures consistent effort, beating yourself up for every little mistake is a form of self-torture. There is no peace in the growth process. Therefore, you should ask yourself this question so as to identify how your experience of personal development would change if you went a little easier on yourself.
